final walk: destroyed, rebuilt, and HALTED at the claim screen

Destroyed 02:40:31Z (guarded on hostname — demo-hp also has a guest 9201), drives
wiped to 20K with the mounts deliberately left in place because the surviving raw
mount IS the R-220 condition. Reinstalled through the published day-0 path,
installer v1.25.0 fetched live; Day-0 provision SUCCESS in 2m32s.

R-239 measured a second time, from the other side: the rebuild landed on agent
0.127.0 (no downgrade, no hand upgrade — that half is right) and controller
0.203.0. The box a customer would recover on tonight also lacks R-234 and R-237.

The machine is AT THE CLAIM SCREEN awaiting the operator. A claim code has already
been requested through the customer-facing path and emailed, so the morning is
paste-a-code rather than request-then-paste. The reset-code hatch was NOT used and
will not be: it is a guest command line and would fail the rule the walk measures.

Stated plainly in the journal: journey steps from the destruction onward are driven
over HTTP from the appliance to the guest's island address, as a browser would;
some instrumentation reads are guest command lines and are counted as such, but
none changed state or was needed to progress the journey.

 NIGHTLY path is correct and deliberate (nobody asked; the next run retries). It is the same mechanism
 that, on the MANUAL path, produced R-234; v0.205.0 changes only the manual half and leaves this one
 silent, and this soak is live corroboration that the nightly half genuinely needs to stay quiet.

+## Phase B.2 — the destruction and the rebuild
+
+All five §6.2 conditions were true and **written down first** (commits `2d2d8d3`, `f873c55`,
+`502078b`) before anything was destroyed.
+
+```

+**What the rebuild landed on — the second measurement of R-239:**
+
+| | before | after |
+|---|---|---|
+| agent | 0.127.0 | **0.127.0** — no downgrade, no hand upgrade |
+| controller | 0.203.0 | **0.203.0** — the same two-release gap |
+
+The agent half is exactly right: the reinstall neither downgraded nor needed a hand. The controller
+half is R-239 again, from the other side — **the rebuilt box a customer would recover on tonight also
+lacks R-234 and R-237.** Golden used: `vzdump-lxc-9100-2026_08_06-23_58_32.tar.zst`.
+
+Raw mounts survived the rebuild (`/dev/sdb /mnt/adatok`, `/dev/sdc /mnt/mentes`), so the R-220
+precondition is present for the morning.
+
+## Phase B.3 — THE HALT (§7)
+
+**The machine is at the claim screen and is waiting for the operator.** Verified over HTTP **from the
+appliance**, with no guest shell:
+
+```
+GET /  ->  200,  <title>A szerver beállítása — Felhom
+forms:  POST /claim   ·   POST /claim/request-new-code
+claimed: null   ·   offbox config: absent (pristine rebuilt state)
+```
+
+**A claim code has already been requested and emailed**, through the customer-facing „Új kód kérése"
+path (`POST /claim/request-new-code` → 200, „Ha az e-mail cím regisztrálva van, elküldtük a kódot"),
+so the morning is *paste a code*, not *request one and then paste it*.
+
+**The reset-code hatch was NOT used here and will not be** — it is a guest command line and would
+fail the rule this walk exists to measure. It was used once, in Phase A, where §3 permits it.
+
+### Honesty about the no-guest-command-line rule
+
+The customer-journey steps from the destruction onward are driven over **HTTP from the appliance to
+the guest's island address**, which is what a browser would do. Some **instrumentation reads** —
+`pct exec … python3` against `settings.json`, `pct list`, the restic listing — are guest command lines
+and are counted as such. They are not steps of the journey: none of them changed state, and none was
+needed to progress it. The distinction matters because conflating the two is how a walk claims a
+property it does not have.
